    2121== Throughput vs. SNR ==
    22 This test measures the achieved throughput of each PHY rate between two WARP v3 nodes running the 802.11 Reference Design. One node acts as AP, the other as a STA. Traffic is generated locally via the LTG framework; measurements are extracted from the nodes via [../../wlan_exp the experiments framework]. The nodes' RF interfaces are connected via a coax cable and a variable attenuator. The attenuation is swept from 70dB to 99dB in 1dB steps.
     22This test measures the achieved throughput of each PHY rate between two WARP v3 nodes running the 802.11 Reference Design. One node acts as AP, the other as a STA. Traffic is generated locally via the LTG framework. The traffic is generated with a payload of 1400 bytes (for an overall transmission length of 1428 bytes when both the 802.11 MAC header and FCS bytes are included). Measurements are extracted from the nodes via [../../wlan_exp the experiments framework]. The nodes' RF interfaces are connected via a coax cable and a variable attenuator. The attenuation is swept from 70dB to 99dB in 1dB steps.

    179 This test measures the achieved throughput of each PHY rate between two WARP v3 nodes running the 802.11 Reference Design. One node acts as AP, the other as a STA. Traffic is generated locally via the LTG framework; measurements are extracted from the nodes via the [wiki:../../wlan_exp experiments framework]. The nodes' RF interfaces are connected via a coax cable and 50dB attenuation.
